Abstract
Methods for management of encoding complexity for image and video encoding, for example for algorithms belonging to the JPEG 2000 family of standards, where the encoding process targets a given compressed size (i.e. a total coded length) for the image or for each frame of a video sequence. A set of methods for complexity constrained encoding of HTJ2K code-streams, involving collection of local or global statistics for each sub-band (not for each code-block), generation of forecasts for the statistics of sub-band samples that have not yet been produced by spatial transformation and quantization processes, and the use of this information to generate a global quantization parameter, from which the coarsest bit-plane to generate in each code-block can be deduced. Coded length estimates can be generated in a manner that enables latency and memory to be separately optimized against encoded image quality, while maintaining low computational complexity.
